Hints appear immediately after comma in object literal

[njx]

At the top level of a file in a JS project that will generate some heuristic hints, type: { foo: bar,

Result: Code hints pop up after the comma. There are two problems with this: (1) it's not clear to me that hints are appropriate here since I'm about to type another key, so there should be no completions; (2) the first item in the hint is selected, so when I hit Return it inserts that item, which is not what I want here since I usually create a newline after a comma.

I've seen this happen in other comma contexts as well--for example, after typing a comma in a var list.

I have a fix for this issue.
